Quartz countertops are popular in kitchens and bathrooms because of their durability, aesthetics, and easy maintenance. However, like any surface, quartz can get stained by spills and over time. Here is a detailed guide on identifying and removing stains from quartz countertops.
What Causes Stains on Quartz?
Quartz is non-porous, so spills and stains remain on the surface rather than absorbing into the material. Common causes of staining include:
- Food and Beverages – Coffee, tea, wine, juice, and oils can stain quartz. Acidic foods like tomatoes and citrus fruit can etch the surface.
- Hair and Cosmetic Products – Dyes, perfumes, and makeup can leave residual stains.
- Household Chemicals – Cleaners, paints, and bleaches may discolor the quartz.
- Metal Marks – Pans, utensils, and jewelry can leave grey/black marks due to metal transfer.
- Mold and Mildew – Moisture buildup promotes mold growth leaving green/black stains.
- Hard Water Marks – Mineral deposits from tap water when left to dry.
- Scratches and Etching – Cutting directly on the counter can scratch the surface making it prone to staining. Acidic spills can etch the quartz.
Identifying Quartz Stains
To identify stains, examine the countertop closely under good lighting. Note the stain’s size, shape, color and texture. This gives clues to the cause:
- Food stains – Localized, shaped like the spilled item. Brown, yellow, orange or red.
- Chemical stains – Irregular shapes. Rust-colored or bleached sections.
- Hard water marks – Clustered spots. White, cloudy appearance.
- Mold/mildew – Black, green or orange spots with fuzzy texture. Concentrated in moist areas.
- Metal marks – Gray/black marks matching the shape of pans/utensils.
- Etch marks – Large cloudy white areas with rough texture. Caused by acidic spills.
- Scratches – Thin white lines in a pattern indicating direct cutting on the surface.
How to Remove Stains from Quartz Countertops
Cleaning Supplies
- Mild liquid dish soap
- White vinegar
- Baking soda
- Hydrogen peroxide
- Soft clean cloth
- Magic eraser sponge
Stain Removal Methods
- For food stains, mix dish soap with warm water and scrub with a soft cloth or sponge. Rinse and dry completely.
- For oily stains, apply baking soda and rub gently with a damp cloth. Rinse and dry thoroughly.
- For chemical/dye stains, use a paste of dish soap and hydrogen peroxide. Let it sit briefly before scrubbing and rinsing.
- For hard water marks, wipe with equal parts vinegar and water. Rinse and dry the surface completely.
- For mold/mildew, mix hydrogen peroxide and baking soda into a paste. Apply and let sit for 5 minutes before scrubbing. Rinse and dry fully.
- For metal marks, use a magic eraser sponge dampened with vinegar. Rub gently and rinse.
- For etch marks and scratches, there is no DIY fix. Professional quartz polishing or refinishing is required.
Caution: Avoid using harsh cleaners like bleach, ammonia, or abrasive scrubs as these can further damage the quartz. Always thoroughly rinse and dry the countertop after applying any cleaning solutions.
Tips to Prevent Staining
- Use cutting boards and trivets to protect quartz from cuts and heat damage.
- Clean up spills immediately before they have a chance to set in.
- Regularly clean quartz with a mild soap and water to prevent buildup.
- Re-seal quartz annually with a penetrating sealer to reinforce stain resistance.
- Avoid letting water or cleaning products pool on the surface. Always thoroughly dry quartz.
- Have any deep scratches repaired quickly by a pro to avoid staining in damaged areas.
With proper cleaning and care, quartz countertops can remain beautiful and stain-free for many years. Act promptly when stains occur and utilize the appropriate techniques to remove them. For stubborn stains that do not respond to DIY methods, contact a professional stone restoration company.
Frequently Asked Questions About Stains on Quartz Countertops
Can all stains be removed from quartz counters?
No, deep etching and scratching cannot be repaired with home methods. Professional refinishing or replacement may be needed for severe damage. But most common stains can be removed with the proper cleaning techniques.
What is the best quartz countertop cleaner?
For routine cleaning, a mild pH-neutral soap and water is best. Avoid harsh cleaners which can strip the finish. For stain removal, gentle solutions like hydrogen peroxide, vinegar and baking soda work well.
How can I restore the shine to a stained quartz countertop?
Use a quartz-specific polishing cream after deep cleaning to restore the surface shine and smoothness. Avoid wax or sealants not formulated for quartz. Re-sealing annually helps maintain luster.
Why does my quartz counter get so many water marks?
Hard water minerals are the culprit. Squeegee the surface after washing to minimize water spots. Wipe up spills before they dry. Use a 50/50 vinegar and water solution to remove existing marks.
Should you seal quartz countertops?
Sealing is not mandatory, but helps reduce staining and etching. Use a penetrating sealer made specifically for quartz every 6-12 months. Avoid film-forming sealants which can yellow over time.
Conclusion
Quartz countertops are prone to stains from spills, chemicals, and regular use. But with some diligence and the proper cleaning techniques, these stains can be effectively removed. Identify the stain type and use the appropriate cleaner. Prevent future stains by acting quickly on spills, using trivets and cutting boards, and sealing regularly. With regular care, quartz countertops can stay beautiful for many years.
